What is the role of platelet transfusion in thrombocytopenia?

• A. It is indicated when platelet count is less than 10,000 or in life-threatening bleeding situations.
• B. It is used routinely to prevent bleeding at any platelet count.
• C. It is contraindicated in all forms of bleeding.
• D. It is used to dissolve clots by enzymatic action.

Answer: (A)

Platelet transfusion in thrombocytopenia is about using platelets to prevent or treat bleeding by raising the platelet count when it’s critically low or when bleeding is actually occurring. In a stable patient without active bleeding, a practical threshold is around 10,000 platelets per microliter; below this level the risk of spontaneous mucosal and cutaneous bleeding increases, so transfusion helps maintain hemostasis. In contrast, if there is life-threatening bleeding or a patient needs a high-risk procedure, platelets are transfused to rapidly restore hemostasis, even if the count isn’t extremely low.

This intervention does not dissolve clots—that action comes from anticoagulant or thrombolytic therapies. Platelet transfusion is not a blanket, routine measure for every platelet count because there are risks (reactions, alloimmunization, infections, volume overload) that must be weighed against the potential benefit.
